The utility model relates to a low-resistance pipeline filtering device which comprises a filtering barrel main body 1, wherein a filtering cavity 2 is arranged in the filtering barrel main body 1, a filtering component 3 is arranged in the filtering cavity 2, a first pipeline 11 is arranged on one side of the filtering barrel main body 1, which is positioned on the other side of the filtering component 3, a second pipeline 12 is arranged on the other side of the filtering barrel main body 1, the first pipeline 11 is provided with a water inflow port 111, the second pipeline 12 is provided with a water outflow port 121, the filtering component 3 comprises a first water filtering net 31, a second water filtering net 32, a third water filtering net 33 and a fourth water filtering net 34 which are sequentially arranged, gaps are arranged between the first water filtering net 31, the second water filtering net 32, the third water filtering net 33 and the fourth water filtering net 34 and the top end or the bottom end of the filtering barrel main body 1, and the four gaps jointly form an S-shaped channel. When the pipeline filter device is used, water flows into the filter cartridge main body 1 through the water inflow port 111 and then flows through the filter assembly 3, when the water flow is turbulent, the water flow can flow into the next filter screen by virtue of the S-shaped channel preferentially, so that distributed filtration is realized, the filtration resistance is automatically reduced, the service life of the pipeline filter device is prolonged, and finally, the filtered water flow is discharged from the water outflow port 121.

Preferably, a drain 13 is also provided at the bottom of the filter cartridge body 1. The drain 13 facilitates the discharge of impurities and the like laminated on the bottom of the filter cartridge body 1, and facilitates the cleaning of the filter cartridge body 1.

As an embodiment, the drain 13 is provided with a drain valve 131. When the drain 13 is not in use, the drain 13 is closed by the drain valve 131, so that unfiltered water flow is effectively prevented from being discharged from the drain 13.

Preferably, a first gap 311 is provided between the first water filtering net 31 and the bottom end of the filter cartridge main body 1, a second gap is provided between the second water filtering net 32 and the top end of the filter cartridge main body 1, a third gap is provided between the third water filtering net 33 and the bottom end of the filter cartridge main body 1, a fourth gap is provided between the fourth water filtering net 34 and the top end of the filter cartridge main body 1, and the four gaps together form an S-shaped channel. The height of the first gap 311 is D1 (the heights of the four gaps are all the same), the height of the filter cavity 2 is D2, and a number ratio of 1:16 exists between the D1 and the D2. The height of the gap cannot be too large, otherwise, adverse effect is brought to the filtering quality of water flow, otherwise, the filtering resistance generated by the filtering component 3 cannot be effectively reduced, and experiments prove that when the height of the gap occupies one sixteenth of the height of the whole filtering cylinder main body 1, the problems can be effectively solved, and the filtering resistance and the filtering quality are not influenced.
